I'm thinking about buying a nokia 7650. So a few questions

* is it possible to use tomtom on the 7650?
* if yes? how does it works with the maps, the 7650 doesn't have external memory ..
* if you can choose between the nokia 3650 and the 7650 which would you buy?

3560, because of mmc card.
7650 is useless with such a small memory
